Features and Function of the Sunpak PZ40X
Welcome to the worldwide family of Sunpak Owners. Your Sunpak PZ40X is
specially designed for NIKON AF-SLRs as well as some Nikon type digital
cameras. The PZ40X can also work with cameras having a non-dedicated,
single-contact hot shoe. Your new PZ40X has many unique features; please take
a few minutes to read this owner's manual carefully.
This owner's manual is written for four groups of NIKON cameras; Group A, B, C,
& D as follows:
Your NIKON
* Multi-step Auto Power Zoom function automatically provides optical flash coverage
matched to the focal length of the lens in use. (24-80mm)
* Super-compact size. This unit is 40% smaller and 2-1/2 oz. (70g) lighter than previous
flash units with the same features and power output, making it far easier to handle
on-camera, while taking up little space in your camera bag.
* With A-group cameras, you can use the PZ40X in the 3D Multi-Flash mode (with D-type
lens only) and Multi-Flash mode (both modes employ a pre-flash for accurate measurement
of distance to subject).
* With A-, B- and C-group cameras, the TTL Auto Mode calculates and outputs the optimal
flash level automatically.
* With D-group cameras, you can use the D-TTL mode for the most precise flash-exposure
management.
* A large, easy to read LCD panel displays all the information needed to monitor and control
all flash settings. The panel can be illuminated for easy reading in dark conditions.
The data display remains on for 20 seconds after pressing the display button.
* The PZ40X has a built-in auto-focus assist light, which comes on automatically to aid
auto-focusing at low light levels.
* The PZ40X provides five Manual flash output settings, from full power to 1/16.
* The PZ40X has a power-saving function that turns the unit off automatically if it hasn't
been used for 5 minutes. This energy-saving feature reduces battery consumption.
* The PZ40X flash head can be tilted upward incrementally to a full 90 degrees (vertical),
for convenient bounce flash capability.

* When using the PZ40X on your camera, please hold your camera and not the flash. If
you hold onto the PZ40X only, your camera may slip off the flash foot and be damaged,
or the weight of the camera may damage the flash foot.
*If you use PZ40X with cameras other than NIKON AF series SLRs, you can only use it
in Manual Mode. Please refer to Page 17.
*Depending on the type of lens used, the distance may not be indicated on the LCD
Display.
Important: Flash coverage limitations
When using a lens with a focal length less of than 24mm, the PZ40X will not cover the
entire field of view, and the edges and corners of the image will be dark. Also, the overall
exposure may not be correct. Please use this unit with lenses of 24mm or greater focal
length.

3DMULT is displayed as shown in the figure
at right. (The last setup will be displayed if a

displayed when using group B- and C-group
cameras.) In response to a signal from the camera, the flash unit calculates the
correct flash exposure based on the film speed, sets the aperture instantly, and
displays the effective TTL flash range on the PZ40X LCD panel. The flash unit
determines the optimum amount of light required for a proper exposure with films
from ISO6 to 6400. The available range will be displayed when you partly depress
the camera's shutter release, or when the Ready Light is on.
The flash range is from 1.5 ft to 100 ft (0.5 to 32m) and is indicated by means of a
bar graph. An asterisk indicates distances greater than 100 ft (30m).

There are five power-output settings available with the PZ40X in manual mode,
from full power to 1/16 power. First, push the Mode Selector button continually
until “M” is displayed. The flash will then be in the Manual mode. Please refer to
the Chart 1 on page 15 for details on setup.
Here are some situations when manual mode is desirable or useful:
1. Daylight synchronization (Flash is used outdoors to lighten shadows or when
the subject is photographed against a strong backlight)
2. When certain focal-length length lenses will be used, such as fisheye type.
3. When a motor drive or an auto-winder will be used.
4. When a number of flashes are used together.
Note: An arrow in the LCD display indicates that the maximum flash range of
100 ft. (30m) has been exceeded.

When the subject is within the Auto Effective Range and there is enough light, the
"Auto OK" symbol in the LCD display will blink for about 2 seconds after the flash

If the symbol goes out, then there was not enough light for an exposure. In that
case, either move closer to the object or select a larger aperture.
Even if the subject is within the Auto Effective Range, the "Auto OK" symbol may
not blink due to the color of an object (dark color with low reflectivity).
